Continuous furnaces are the right choice for processes with fixed cycle times such as drying or pre-heating, curing or degassing, etc.. The furnaces are available for various temperatures up to a maximum of 1000 °C. The furnace design depends on the required throughput, the process requirements for heat treatment and the required cycle time. The conveyor technology (e.g. belt, rollers) is tailored to the required working temperature and the geometry of the charge. The conveyor speed and the number of control zones are defined by the process specifications.

Alternative furnace design subject to process specifications:

Conveyor concepts

Conveyor belt

Metal conveyor belt with adjusted mesh gauges

Drive chain

Roller conveyors

Pusher-type furnace

Heating systems

Electric heating, radiant or convection

Direct or indirect gas-firing

Infrared heating

Heating with the use of external heat sources

Temperature cycles

Control of working temperature across the whole length of the furnace, such as for drying or pre-heating

Automatic control of a process curve applying defined heat-up, dwell and cooling time

Control of a temperature curve including a final quenching of the charge

Process atmosphere

In air

In non-flammable protective or reactive gases such as nitrogen, argon or forming gas

In flammable protective or reactive gases such as hydrogen incl. the necessary safety technology
